31.2. 设置全局构建默认值
您可以通过两种方式设置全局构建默认值：
31.2.1. 使用 Ansible 配置全局构建默认值
在集群安装过程中，可以使用以下参数来配置 BuildDefaults 插件，该插件可在清单文件中配置：
-
openshift_builddefaults_http_proxy -
openshift_builddefaults_https_proxy -
openshift_builddefaults_no_proxy -
openshift_builddefaults_git_http_proxy -
openshift_builddefaults_git_https_proxy -
openshift_builddefaults_git_no_proxy -
openshift_builddefaults_image_labels -
openshift_builddefaults_nodeselectors -
openshift_builddefaults_annotations -
openshift_builddefaults_resources_requests_cpu -
openshift_builddefaults_resources_requests_memory -
openshift_builddefaults_resources_limits_cpu -
openshift_builddefaults_resources_limits_memory
例 31.1. 使用 Ansible 构建默认配置示例
# These options configure the BuildDefaults admission controller which injects
# configuration into Builds. Proxy related values will default to the global proxy
# config values. You only need to set these if they differ from the global proxy settings.

# Or you may optionally define your own build defaults configuration serialized as json
#openshift_builddefaults_json='{"BuildDefaults":{"configuration":{"apiVersion":"v1","env":[{"name":"HTTP_PROXY","value":"http://proxy.example.com.redhat.com:3128"},{"name":"NO_PROXY","value":"ose3-master.example.com"}],"gitHTTPProxy":"http://proxy.example.com:3128","gitNoProxy":"ose3-master.example.com","kind":"BuildDefaultsConfig"}}}'
